Top Smart Contract Languages in 2024: Solidity, Rust, and Motoko

5 Jun 2024

Welcome to Dapp Mentors! In this article, we'll delve into the top three programming languages for blockchain development: Solidity, Rust, and Motoko. As a seasoned blockchain developer and educator, I'll share my expertise to help you transition into web3 development.

Solidity: The Favorite

Solidity is our top choice due to its simplicity, ease of use, and wide community support. It's the most widely used language for blockchain development, and its simplicity makes it an excellent choice for beginners. However, it has limitations:

  • Scalability: Solidity is not very scalable, especially on layer one. This limitation has led to the development of layer two solutions built on top of Ethereum.

  • Security: Solidity is not as secure as Rust. While it's widely adopted, its security vulnerabilities can be a concern.

Solidity Code Example

In my opinion, Solidity is a great language for beginners, but its limitations make it less suitable for large-scale applications.

Top Companies Using Solidity

  • Ethereum
  • Binance Smart Chain
  • Polygon Network

Rust: The Secure and Scalable

Rust is a more mature language than Solidity, offering security and scalability. Its advantages include:

  • Security: Rust is a more secure language than Solidity, making it an excellent choice for high-stakes applications.
  • Scalability: Rust is highly scalable, making it suitable for large-scale blockchain applications.

Rust Code Example

In my opinion, Rust is a powerful language that offers a great balance between security and scalability, making it an excellent choice for large-scale blockchain applications.

Top Companies Using Rust

  • Solana
  • Polkadot
  • Stellar (uses Rust under the hood for their smart contract framework Soroban)

Motoko: The Newcomer

Motoko is exclusive to the Internet Computer Protocol (ICP) ecosystem. While it's highly scalable and performant, its adoption is limited, and it's relatively new. Its advantages include:

  • Scalability: Motoko is highly scalable, making it suitable for large-scale blockchain applications.
  • Ease of use: Motoko is easy to learn and use, even for developers new to blockchain development.

Motoko Code Example

In my opinion, Motoko is a promising language that offers a unique set of features and advantages. Still, its limited adoption and exclusive nature make it less versatile than Solidity and Rust.


In conclusion, each language has its strengths and weaknesses. Solidity is simple and widely adopted, Rust offers security and scalability, and Motoko is unique to ICP. Consider learning Rust for its versatility across blockchain networks. Join the conversation, and share your thoughts on your favorite programming language and why you prefer it.
